IMPROVEMENT IN WALL-PUMPS.

Specification forming part of Letters Patent No. 195,781, dated October2, 1877; application filed February 17, 1877.

To all whom it may concern:

Be it known that we, ROBERT WHITE, of the city of Brooklyn, county ofKings, and State of New York, and ROBERT WALLACE and DAVID MORITZ, bothof the city of New York, county of New York, and State of New York, haveinvented a new and Improved VVall- Pump, of which thefollowing is aspecification:

Figure l is a front View, partly in section, of our improved wall-pump.Fig. 2 is a detail face view, partly in section, showing the connectionof the plunger-rod with the operating mechanism. Fig. 3 is a detailcrosssection on the line 0 c, Fig. 1; Fig. 4, ahorizontal section on theline K K, Fig. 1; Fig. 5, a side view of a modification of theanlifreezing attachment.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention has for its object to improve the construction of frame,cylinder, and operating mechanism of a wall-pump, which is a pimpattached to a frame that is adapted to be fastened-to the face of a wallor other vertical support.

The first feature of this invention consists in supplying the frame ofthe pmnp with a hinged strap, whereby the cylinder is clamped intoposition vertically, said strap permitting the ready removal of the samefrom the frame for purposes of repair and otherwise, and permitting alsothe rotation of the same within the space that confines it to the frame.

The invention also consists in swiveling the upper end of the bracket,by which the handle that works the pinup is held in place in a socketformed at the upper end of the pump-frame.

It also consists in rendering the plunger-rod sectional, so thatwhenever the plunger is to be removed the rod may be taken to pieces,the upper head of the cylinder unfastened, and the plunger withdrawn,all without displacing the bracket or the handle.

The fourth feature of the invention has reference to the manner ofholding the swivelring, which is formed at the lower end of thelever-bracket, it being in this placed under the cylinder-head, incontradistinetiou to placing the ring over the head, as has heretoforebeen usually done. This allows us to unscrew the head in the manneralready stated, and remove the plunger without displacing the bracket;whereas, it the bracket-ring rests on the cylinder-head, this ring mustfirst be removed, and with it the bracket, before the head can bedetached.

The invention also consists in joining the lever which operates theplunger, by a link, to the bracket of the pump, thereby producing a verydesirable antitriction connection; also, in forming wings on theahandleto lap over the pivot-pin that connects the said link to the bracket,and finally in applying a crank-pin to the suction-pipe of the pumpdirectly below the supply-valve, so that, by vibrating said pin by meansof a handle with which it is provided, the supply-valve can be heldopen, and all the water contained within the pump be discharged into thewell or reservoir, whereby the pump is prevented from freezing inwinter.

In the accompanying drawing, the letter A represents the frame of ourimproy'ed pump, said frame being made of cast metal or other suitablematerial of proper size and shape. From its face projects a pair ofsaddles, a. a, for the support of the pump-cylinder B, which is placedinto the hollow of the saddles, and retained in a vertical position by astrap, 0, that is hinged by a pin, 1), to lugs projecting from the frameA, as clearly indicated in Figs. 1 and 4. These lugs are shown to beparts of the saddles a a, but may be separate pieces, if desired.

The part which we have termed the strap O is a piece of metal of nearlysemicircular form, having the vertical pin 11 projecting from one end ofthe semicircle, and a loop or eye, (I, from the other end. A screw, 0,which is by its head held fast to the frame A, passes through the eye(I, as shown in Fig. 4, and a nut, f, applied to the screw e, bears uponthe eye (I, and crowds the strap 0 tightly against the cylinder 13. 3yunfastening the nut f the st *ap (I can be. liberated to swing on itspivot b, and to permit the ready removal or reversal of thewimp-cylinder.

The plungerrod I) of the pump extends upwardly through a hole in theupper end of the bracket I as shown, the bracket It being that part ofthe pump to which the operatinghandle F is pivoted or connected. Thelower end of this bracket forms a ring. 9, that encircles the upper partof the pump-eylinderB, and that is held in place by a cap or head, 1:,screwed upon the upper end of the pump-eylindcr, the said cap hconstituting, virtually, the upper head of the pump-eylinder. The upperendj of the bracket 1) is cylindrical, its inner bore being of a size toadmit the rod I), and its outer diameter corresponding to the apertureformed in the upper cross-bar i of the bracket E. This cylinder j, soformed at the upper end of the bracket E, and necessarily concentric tothe ring g, permits the rotation of the bracket E on the frame A,without necessitating the displacement of any of the parts, excepting,perhaps, a slight loosening of the head h that clamps the ring g tightagainst a shoulder formed on the punip-cylinder. Vt'e are thus enabled,without taking the pump to pieces, to reverse the bracket E, and with itthe position of the handle, and allow the bandle to be applied either tothe right or left hand side of the pump. \Yhen such reversal washeretofore desired it was, as far as we know, always necessary tounfasten the handle before the reversal could take place.

The plunger-rod I) is made in two parts, of which the lower part I isthe plunger-rod proper, while the upper part m connects with the leverF, and is guided in the cylinder j. The two parts I m of the plunger rodare screwed together at a short distance below the point at which thelever F connects with the plunger-rod by the pin a. By separating thesetwo pieces, I m, in the manner imlicated in Fig. 2, the removal of thehead h from the ptunpcylinder and the withdrawal of the pump-plungerfrom within the cylinder, is facilitated without requiring the removalof the lever F, whereas heretofore, as far as we are informed, it wasimpossible to withdraw the plunger-rod from the pump-cylinder withoutfirst unfastcnin g such rod from the operatinglever. This we avoid. Thelever F is, by a pin, 0, pivoted to a crank or link, G, which, byanother pin, p, is pivoted to the bracket E, so that in vibrating thelever F for operating the pump it will not only swing on the pivot 0,but also on the pivot 1), this double motion serving to compensate forthe varying distance between the pivots n and 1) during the operation ofthe pump.

We deem this link-connection of the lever with the bracket superior topositive or direct connection, inasmuch as much friction is avoided bythe arrangement.

0n the lever F we form a pair of projecting wings, q, which lap over andstraddle the ends of the pivotpin p, and serve to hold said pivot-pin inplace on the bracket without requiring it to be fastened on the bracketor link by other fastening, such as screw threads, transverse pins, &c.

In the supply pipe II, which enters the lower end of the pump-cylinder,is pivoted, by a pin, 1', a crank, I, the pin 1' having a projectinghandle, s, on the outside of the supplypipe, for the purpose ofpermitting it to be vibrated on its bearings.

'hen the pump is to be set at rest in winter we elevate the crank I bymeans of the handle 8, and thereby raise the lower valve t of the pump,and with it, also, the valve 1!, which is usually contained in theplunger, all as indicated in Fig. 1. In thus raising the crank, thevalves 1 u are opened, and all water contained within the pump-cylinderis allowed to flow down into the supply pipe, whereby the freezing up ofthe pump is entirely avoided.

In order to permit this opening of the valve u it is, of course,necessary to first bring the plunger down to its lowermost position 011the cylinder. The pin 1' may be either directly passed through the bodyof the supply-pipe II, as in Fig. 1, or it may be caused to extendthrough a lateral enlargement, w, of said supply-pipe, as indicated inFig. 5.

If the lever F is directly pivoted to the bracket E, the linkconnectionmay be made with the plunger-rod, which, however, we do not claim inthis application; but under such construction the cylindrical extensionj of the bracket E need not be made hollow, but may be solid. A similarcrank, I, may be placed in a force-pipe, if the same contains a valve.
